Extended Medicare Coverage (Pre TWIIA)

Social Security beneficiaries who lose benefit entitlement due to performance
of SGA, but continue to be disabled, were eligible for extended Medicare
coverage. The extended coverage was for a minimum of 39 months following
the conclusion of the nine-month TWP. The 39-month period was derived from
adding the original 15-month EPE re-entitlement period (pre-1988) to the
24-month pre-TWIIA extended Medicare coverage (1/88 to 9/00).
